Hunter x Hunter follows Gon Freecss, a young boy who dreams of becoming a Hunter to find his long-lost father, Ging. Along the way, he befriends Killua, Leorio, and Kurapika as they face dangerous trials, including the grueling Hunter Exam. The series delves into their personal journeys as they confront powerful foes and uncover deep secrets about their pasts, while exploring themes of friendship, morality, and personal growth.

Central to the story is the concept of Nen, a power system that shapes the characters' abilities and battles. Major story arcs, like the Chimera Ant Arc, explore complex themes such as evolution and humanity. Despite frequent hiatuses, Hunter x Hunter is widely praised for its intricate world-building, unpredictable plot, and philosophical depth, making it one of the most celebrated anime and manga series.
